String serviceStart = '';       
dom.XmlNode envelope = doc.createRootElement('Envelope',soapNS, 'soap');
dom.XmlNode bodyhead = envelope.addChildElement('soap:Header',null,null);
dom.XmlNode security = bodyhead.addChildElement('Security',xsi,'');
dom.XmlNode ContactBdy = bodyhead.addChildElement('ns:Contact', null, null);
dom.XmlNode EmailsBdy = ContactBdy.addChildElement('ns:Email', 'EmailType="03"',  null);
EmailsBdy.addChildElement('ns:EmailAddress',null,null).addTextNode('[email protected]');

EmailType is not a namespace, it's an attribute. The following change to your code should work.

dom.XmlNode EmailsBdy = ContactBdy.addChildElement('Email', null, 'ns');

The arguments to addChildElement (see the XmlNode documentation) are:

  • name
  • namespace
  • prefix

so each call to that should be supplying all 3 values given that the XML you need to generate has several namespaces:

private static final String PAYLOAD_NS = 'http://...';
private static final String PAYLOAD_PREFIX = 'ns';

EmailsBdy.addChildElement('EmailAddress', PAYLOAD_NS, PAYLOAD_PREFIX)
